Think about it: most of the best horror movies throw in a little bit of mystery. Jump scares have the biggest impact when you’re not sure what’s around the corner, behind the door, under the floorboards… or in your mailbox. Grab a Mystery design today, and a green slime bag will soon arrive with a surprise design lurking inside. Sold-out classics from our back catalog, leftovers from limited editions, and everything in between!

Quantities are limited on these, so be sure to act fast! You’ll receive a randomly selected design that isn’t available elsewhere on our site. This is an *all sales final* item and is ineligible for returns and/or exchanges. Surrender yourself to the unknown - send a surprise gift to your future self!

Please note: Receiving duplicate designs is a possibility, due to the limited nature of Mystery options available.
